The machine may have the well-known reciprocating. carbon-carrier toholdcarbons interleaved with the plies of, the Web, and a displaceableplaten to allow the web to be straightened out for the carbons to bewithdrawn from the written to a fresh section of the Web. Before,restoring; the platen the web is usually drawn forward by hand to en-,

= gage a leading-edge gage so as to bring the severing line to registerWith a usual severing knife, while the carbons'may be stripped inopposite direction. r

' In cases where the web-plies are loosely superposed, and also in caseswhere the carbons extend near to the top edge of eithera fan vfold or aloose ply web, only -a small edge-portion of the top of the webis leftfree of carbon. It is diflicult or impossible for the operator to graspthe web at the top edge when gaging thesame and stripping the carbons. II c The. invention therefore provides a selfreleasing paper-clamp underthe control of the operator, which will nip, the narrow edge of the webabove the carbons to hold the web at the carbon-stripping operation.This .nipper is settable upon a gage-bar which usually forms the upwardcontinuation of a front collatingtable and which is displaceabletogether with the platen in straightening out the carbons preparatory tostrip- A finger-piece may be depressed tonip the paper, while releasingthe finger-piece will release the paper.

Two superposed resilient paper-gripping; open tongues are flatlyarranged upon said gage-bar, said tongues normally spreading apart toreceive therebetween the leading edge portion of the web. The deviceincludes a body-portion slidable upon said'gage-bar "and provided with aset-screw, which ten- Sions the lower tongue slightly against theFigure?) v device, and shows more-clearly the leading said-tonguepermits the leading edge ofthe" Web to slip from the gage-bar into theclamp.

The tongue extends from said body-portion and does not exceed thewidtliof theggagebar, so that the operators finger while pulling the webmay slide along. the gage-bar to be guided thereon until the leadingedge abuts the gaging point. I V

A stud rises centrally from thetongue which lies against the gage-bar,Said stud; extending through a central opening in the other tongue. Theprojecting end ofthe stud. has pivoted thereon a cam-member terminatingin afinger-piece. It is s o arrangedthat depression of the finger-piecewill urge the adjacent resilient tongue to grip the edge of the paper,while releasing the finger-piece will. allow the tongue to snap back toopen position.

Said stud also furnishes the for the leading edge of the web. v

Other features and advantages will hereinafter appear. V

The clamp further includes -a box-"like body-portion or slide 33 uponwhich said tongues are fastened, as by rivets 34 (see Flare 4 Thebody-portion Ehas 'slots 35 in w, ich it receives said tongues and '80also receivesithe gage-bari29 tobe-slidable thereon.

it will be 'noted that this combined gage ,and clamp is a unit structurethat can be removed .fromthe bar and laid aside without .fear ofthepartsiheing lostgthat the tongues 30 and 31, when secured together atone end to the slide 33, are formed to become tensioned open tongues attheir free ends, ready :to ireceive the leading end of the web betweenthem; and that the compressed tongues :are not lcc ked in web-clampingposition, but the fingeris retained upon the depressed-finger-p'ieceuntil "the carbons have been stripped, which makes the clampsemi-automatic.
